SPECIAL PROVISIONS

The following Special Provisions supplement the "Standard Specifications for Road and Bridge Construction," adopted January 1 2022, the latest edition of the "Manual on Uniform Traffic Control Devices for Streets and Highways," and the "Manual of Test Procedures for Materials" in effect on the date of invitation for bids, and the Supplemental Specifications and Recurring Special Provisions indicated on the Check Sheet included herein which apply to and govern the construction of Contract 61M10, Project C-91-124-23, Section 23-00358-00-TL, Indian Trail Road, Ohio St to Pennsbury Ave, Kane & DuPage County and in case of conflict with any part or parts of said Specifications, the said Special Provisions shall take precedence and shall govern.

Indian Trail Road, Ohio St to Pennsbury Ave Section 23-00358-00-TL

Project C-91-124-23 Kane & DuPage County

Contract 61M10

LOCATION OF PROJECT

The project is located in the City of Aurora along E Indian Trail Road (FAU 1503, MUN 1157, and FAU 1509) from Ohio Street to Pennsbury Lane in Kane and DuPage counties. E Indian Trail Road becomes N Aurora Road east of Eola Road. The gross length is 2.917. The net length of the project is 0.814 miles which accounts for several project omissions between the project termini. A location map is shown on the cover of the Plans.

DESCRIPTION OF PROJECT

The scope of work consists of traffic signal modernization at five intersections along E Indian Trail Road (FAU 1503, MUN 1157, and FAU 1509) between Ohio Street and Pennsbury Lane. The five intersections will be integrated into the City’s existing centralized transportation management system. The intersection included are as follows:

STATUS OF UTILITIES (D-1)

Effective: June 1, 2016 Revised: April 1, 2025

The above represents the best information available to the Department and is included for the convenience of the bidder. The days required for conflict resolution should be considered in the bid as this information has also been factored into the timeline identified for the project when setting the completion date. The applicable portions of the Standard Specifications for Road and Bridge Construction shall apply.

Estimated duration of time provided above for the first conflicts identified will begin on the date of the executed contract regardless of the status of the utility relocations. The responsible agencies will be working toward resolving subsequent conflicts in conjunction with contractor activities in the number of days noted.

The estimated relocation duration must be part of the progress schedule submitted by the contractor. A utility kickoff meeting will be scheduled between the Department, the Department’s contractor, and the utility companies when necessary.

The contractor is responsible for contacting JULIE (or DIGGER within the City of Chicago) prior to any excavation work. Please note that IDOT electrical facilities are not part of the one-call locating services, such as JULIE or DIGGER.
